' 6'Claims. (01. 62-95) This invention relates to refrigerators and more an enlarged scale taken along the'line[6+5 of particularly to a construction whereby heat ab- Figure 1. a sorbing fluid may be circulated through brine Figure 7 is a fragmentary view looking atone tubes and effect cooling of the brine and atmosend of the shelf, the view being takenalongth'e phere about the brine tubes.

Another object of the invention is to so arrange This improved device consists of a number ,of the brine tubes that their ends will be connected brine tubes each formed of strong sheet metal. by headers and together with the headers form a Thesetubes are rectangular 'in cross section in device which maybe supported in a horizontal order to provide fiat upper surfaces for the tubes position and employed as a shelf in a counter or and therefore a number of these tubes disposed in 10 chamber of a refrigerator. spaced parallel relation to each other may form 7 Another object of the invention is to provide an a portion of a shelf having a flat uppersurface improved type of fluid circulating coil having its and articles may be set in place thereon without 7 convolutions arranged'in the form of a spiral and being liable to turn over.

The

Figures 3 and 4 and therefore heat absorbing fluid circulated through the coil will first pass through the side portion l2'of a convolution extending through the first brine tube at one side of the shelf and will then pass through the end portion ll of this convolution and back throughthe side portion [3 extending through a brine tube at approximately the transverse center of the shelf which in. the present illustration is brine tube number 6 counting from the bottom of Figure 5.

From this tube the fluid passes through the end.

portion l5 of the convolutionuntil it reaches the side portion I2 of the second convolution and through this side portion which is, located inthe second brine tube. The end portion, Id of this convolution extends through the header 5 above the end portion 14 of the 'first convolution as shown in Figure 3 and the side portion l3 of this convolution passes through brine tube number l.

This staggered arrangement of the convolutions is repeated throughout the width of the shelf and due to this arrangement of the convolutions the cooling action which takes place as the heat absorbing gas is circulated will be evenly distributed throughout the width'oitheshelf and the brine in the brinetubes and headers remain at substantially an even temperature. The side portion l2 of the first convolution and side portion l3 of the last convolution extend through end portions of the header 6 transversely thereof and each of these portions extends outwardly through the outer side Wall of the header for connection with a circulatingsystern for the fluid. Leakage of brine must be prevented and in order to do so there has been provided packing glands I6 each consisting of a cup ll riveted or otherwise firmly secured against the outer side wall of the header and projecting inwardly about the tubing as shown in Figure 6. 'This cup receives packing I8 and is internally threaded for engagement with the threads of a sleeve 19 which when screwed inwardly forces the packing tightly into the inner end of the cup about the tube and forms a very "tight joint. It will of course be obvious that the tubing for circulating'the heat absorbing fluid tion and in the minor details of construction may be resorted to without departing from the. spirit or sacrifici g any of the principles of the invention. I o

I-Iaving thus described the invention what is claimed is:

1. In a refrigerator structure, a plurality of brinetubes spaced transversely from each other and having flat upper side faces, headers extending transversely of the tubes and connected with the tubes with ends of the tubes opening into the headers, theheaders and tubes forming a shelf having end portions adapted to rest upon supports, and a coil for circulating heat absorbing fluid extending throughthebrine tubes and headers and having end portions projecting outwardly for connection with'a circulating system, the portions of the coil extending through the headers being disposed longitudinally thereof in overlapped relation to each other.

2. In a refrigerator structure, a plurality of brine tubes, heads extending transversely of said tubes and connected with ends of the tubes, and a coil for circulating heat absorbing fluid through the tubesand heads having its convolutions arranged in spiral formation and in stepped relationtransversely of each other.

3. In arefrigerator structure, a plurality of tubes and connected with ends of the tubes, and

a coil for circulating heat absorbing fluid through the tubes and heads having its convolutions arranged in steppedrelationtransversely of each other and each after passing through a brine tube extending longitudinally in a head past a plurality of the brine tubes and back through a brine tube to the other head. i

4. In a refrigerator construction, a plurality of brine tubes spaced transversely from each other, bridges connecting ends of said tubes, headers extending transversely of the tubes and connected with the bridges for communication with the tubes, and a coil for circulating heat absorbing fluid having its'convolutions extending through the tubes and headers.

brine tubes spaced transversely from each other, bridgesconnecting ends of said tubes, collars secured about said bridges and projecting from the same, headers secured about the collars and communicating with the tubes through the collars and bridges, and a coil for circulating heat absorbing fluid having portions extending through the tubes and connected by portions extending longitudinally in the'h'eaders.

v 6. In a refrigeratorconstruction, a plurality of brine tubes spaced transversely from each other, bridges connecting ends of said tubes, collars secured about said bridges and projecting from the same, headerssecured about the collars and communicating with the tubes through the collars and bridges, and a coil for circuiating'heat absorbing iluid having its convolutions arranged in stepped relation transversely of each other and each havingportions-extendingthrough a pair of tubes and connected'by portions extending longitudinally in the headers in crossed relation to a plurality of tubes between the said pair of tubes.
